355 Kevlar clutch disk

A little eye candy.

Whoooaaaa!!! That's beautiful....who did it???

I would be happy to share all the pertinent information after the beta testing is complete.

Supposedly, the Kevlar material has a higher coefficient of friction which allows the disk to last 3x longer than the stock organic type (cooked wood fiber). Also the other advantage is a cooler flywheel and pressure plate (less warping with heavy use). There are some special requirements for the install; you can’t just install a new Kevlar disk.

It will be interesting to see the differences between the two materials after testing.

If you want more information leave a # I can call. We are also working on a permanent fix for the rattling flywheel assembly without adding more Klubber.

Hi JH,

I think MANY 355 guys and the Shops that service 355's would be very interested in the pertinent Info:

and a DM Flywheel solution would be a double plus!!!!

Doesn't ClutchMasters rebuild clutches in kevlar also?

What about the 360 F1 clutches?

Stunning to say the least.
I would be concerned on one matter that may or may not apply to Kevlar on a 355 aplication. I have seen cases where if the clutch was slipped, and got too warm, the result was a grabby disc for a while. Any thoughts? Not critisizing, mind you. It just may be something to be aware of.

Matthew,

you are right! nothing so far has topped asbestous (unfortunately). And even the Factories continue to experiment with different composites.

The real solution is likely to come from guys like John Haller above, or the Aircraft Industry or Trucks (18 Wheelers). Racing is to brutal & short term in this case to give long term street success imo.

Good point MM, where this idea came from is the Cummins diesel guys; they are pushing in some applications 1000 ft lbs of torque. The coefficient of friction is greater with Kevlar so we expect there to be less slipping over a stock disk which should translate into less energy going to make heat and more going to rear wheel HP. One of the side benefits might also be 3x expected disk life which has been reported in the Cummins application.

The disk, flywheel and pressure plate iteration will be installed after this years driving season for real world testing, probably September.
